feat: Add link for readonly variables in semantic tokens

[Old-Farmer]

Catppuccin is wonderful and I use it everyday in neovim. But I've found that this colorscheme can't deal with constants well because it doesn't use lsp semantic hl capability. Constants/Readonly vars are always way better using lsp semantic hl than treesitter hl, so I make this pr. Feel free to make some tweeks and give me some feedbacks to improve this pr.

which languages did you check this with?

could you add some screenshots. that helps make the differences clear.

in cpp:

without this setting.
